Back and seat frames h, 2', respectively, are hingedly connected together as at j, see Figs. 3 and 4. An elongate transverse notch 70 is provided in the rearward surface of the back frame It adjacent the top, by which the back frame is pivotally mounted on the said rod 0, and notches 1 are provided in the underside of the seat frame 7?, adjacent its front, adapted to be mounted on the U-shaped rod e and by which the seat frame is swingingly and pendently supported.

Resilient elements or bumpers p are provided on the ends of the rear transverse members b for cushioning the rearward swing of the seat frame.

Bar-this construction, the movement of the seat frame forward will cause the back frame to swing forward also and the seat to be inelined downward, as illustrated in Figs. 6 and 8 to conform with the more natural reclining position of the occupant.

Thus the usual springs and upholstering, having been provided as illustrated in Fig. 1, the occupant of the chair may, by merely shifting his weight backward or forward in the chair, change from an upright to a reclining position or the reverse, as his fancy ma dictate.

, eferring now to Fig. 8: I show a slightly modified embodiment of my chair, in that the seat frame 3 is provided with notches 3* and is supported on a U-shaped transverse rod 2, the equivalent of the rod 0 previously described, but is mounted to rotate in bearings 4, secured on the underside of the side portions of the chair frame. This constructionmay at times be preferable in that no was; equivalent to the recesses 7 in the side members are required, and possible wear on the adjacent upholstered surfaces of the chair is eliminated.

In Figs. 9 to 12 is shown a furthermodificttion of my invention, in that the back frame 17 is relatively shorter and is supplemented by a stationary back section 18 of the chair frame. The back section 17 is pivotal- 1y connected below the section 18 at its upper end on pintles 19 seated in notches 19 in the side members 20; the seat frame 11 being mounted pendently on the U shaped cross rod 12, as previously illustrated in Figs. 1 to 7.

I claim:
